7.6.1 Dolby Ch 1 and Ch 2 (Option)
Each Dolby slot houses a Dolby encoder and transcoder.
•
Decoder Source:
Enables you to route the chosen incoming audio source (SDI or
AES) to the Dolby decoder. See “Block Diagrams” on page 15.
•
Input Status:
Shows the detected audio. If this shows as “PCM”, the incoming audio
is not Dolby and Dolby processing is not active.
•
Decoder Format:
Provides Dolby E/D source information. For example, in the case
of Dolby E, this could be 5.1+2, 7.1, 8x1 etc.
•
Decoder Rate:
Shows the frame rate of the incoming Dolby audio (50 Hz or 59 Hz).
•
Decoder Version:
Shows the version number of the Dolby decoder. The Dolby E
decoder and encoder both have their own software version installed which is
independent from the rest of the unit. Dolby updates this software continually.
•
Metadata Source:
Enables you to choose whether to use the incoming Dolby
metadata when transcoding. Select the Decoder radio button to enable the metadata
or the None radio button to discard it.
•
Dolby Delay Compensation:
Enables you to select delay compensation to maintain
correct alignment.
•
Encoder Version:
Shows the version number of the Dolby encoder. The Dolby E
decoder and encoder both have their own software version installed which is
independent from the rest of the unit. Dolby updates this software continually.
•
SMPTE 2020 Output:
Selects the output line on which to insert a SMPTE 2020 VANC
packet if the output is enabled. The range is from line 8 to line 20 in one-line steps.
It is possible to set a forced association in the SMPTE 2020 metadata which sets the
Secondary Data ID (SDID) values used to identify the VANC packets to 45/02 (pair 1).
To use this control, enable “SDID Pair 1 Forced Assoc” from the Dolby menu under
the sub-menu SMPTE 2020 Output. When enabled, the outgoing 2020 data will be
labelled 45/02 (pair 1).
•
Packet Type:
Selects a method of data mapping for output SMPTE 2020 VANC
packets.
•
A:
SMPTE 2020-2-2008.
•
B:
SMTE 2020-3-2008.
•
Dolby Metadata Output Line Status:
Shows the actual output line number on which
the SMPTE 2020 VANC packet is embedded, as set on the SMPTE 2020 Output
slider. If no line number is selected, “OFF” is displayed.
Note: If the line selected is already in use (by VITC, for example), the VANC
embedding hierarchy will embed the SMPTE 2020 packet on the nearest available
line.
Note:
If the Dolby option is not fitted, the Dolby Ch 1 and Dolby Ch2 menus are grayed out.
